Rtl8821ce new backports support

For those who own Lenovo laptops (V145-15AST for example), good news: in the backport repository, they recently added the 5.7 kernel which natively has the firmware for the rtl8821ce wireless driver, which previously had to be compiled and was not stable...

Re: Rtl8821ce new backports support

Not being very familiar with Debian/Devuan I was wondering if there are any risks or disadvantages in installing a backports kernel. For example, does it make package upgrades unstable? Thanks.

Re: Rtl8821ce new backports support

The backported kernel is drawn from testing and so may be subject to the mandatory transition delay from sid, which may result in vulnerabilities being left exposed for longer than would be the case with the stable kernel.

If you do need the backported kernel then be sure to leave the repository enabled so that it's updated. I've had too many arguments about this over at the MX forums but I'm definitely right big_smile

And note that "unstable" in De{vu,bi}an refers to the package version flux rather than reliability.

EDIT: yay for the rtl8821ce support though, thanks for the update OP.

EDIT2: and watch out for regressions with the backported kernel, the developers are too busy adding new vulnerabilites features to worry about keeping old stuff working.

Thanks. I assume you would want to disable the repository when  upgrading to a new release?

Re: Rtl8821ce new backports support

It doesn't matter actually, the tilde in the package name means that APT will treat it as older than the versions from the new release even if they are technically the same. But having an oldstable-backports repository makes no sense so it should be removed.
